The wandering.shop Mastodon instance (server) is pausing new accounts for probably a few days while they catch up with the growth in activity: "We have gained over 500 accounts and have around 1000 users *active* (up from maybe 100 or so)."
I have set up an account on a Mastodon "instance," which is what Mastodon calls a server, as redbird@wandering.shop. Wandering.shop because a bunch of SF and fantasy writers and fans are there, and one of them was inviting people on the Scintillation Discord server.
I'm still figuring out how Mastodon works and how I want to use it. If I understand this, I can invite people to join that Mastodon instance. If I know you and you want an invitation, ask; I'm screening comments to this post.
This prompted of course by what's happening on/to Twitter, but I was barely using my Twitter account anyway.
